The CRS is a Congressional "think tank" with a staff of around 700. Reports are commissioned by members of Congress on topics relevant to current political events. Despite CRS costs to the tax payer of over $100M a year, its electronic archives are, as a matter of policy, not made available to the public.

Individual members of Congress will release specific CRS reports if they believe it to assist them politically, but CRS archives as a whole are firewalled from public access.

This report was obtained by Wikileaks staff from CRS computers accessible only from Congressional offices.

In 2001, EPA issued a new arsenic rule that set the legal limit for arsenic in tap water at 10 parts per billion (ppb), replacing a 50 ppb standard set in 1975, before arsenic was classified as a carcinogen. The arsenic rule was to enter into effect on March 23, 2001, and water systems were given until January 2006 to comply. EPA concluded that the rule would provide health benefits, but projected that compliance would be costly for some small systems. Many water utilities and communities expressed concern that EPA had underestimated the rule's costs significantly. Consequently, EPA postponed the rule's effective date to February 22, 2002, to review the science and cost and benefit analyses supporting the rule. After completing the review in October 2001, EPA affirmed the 10 ppb standard. The new standard became enforceable for water systems in January 2006. Since the rule was completed, Congress and EPA have focused on how to help communities comply with the new standard. In the past several Congresses, numerous bills have been offered to provide more financial and technical assistance and/or compliance flexibility to small systems; however, none of the bills has been enacted.
